What are the advantages of using corn starch rather than flour?
Corn starch thickens with a satiny smoothness and glossy appearance. It adds no taste of its own to mask the flavor of foods. Recipes thickened with corn starch have a brighter, more translucent appearance than those thickened with flour. Corn starch also blends more easily with cold liquids than flour because it doesn’t absorb liquid until it’s cooked.
